The stone here is a large bluestone, but there is a pale gray the size of a palm on the big bluestone, he swept to the cave wall and grabbed the wall with gecko skills, pointed his finger at the gray position, and a half-inch-thick stone shattered in the click, and he looked inside and saw a roll of leather made of unknown things inside.

took out the leather and fell to the ground to unfold, there were some twisted tadpole texts on it, fortunately, Yu Nan specially downloaded the comparison table of various texts for the sake of insurance, and after scanning, the system projected the content of these tadpole texts.

"Xuanyuan penance cultivation Taixuan Sutra, the three thousand maidens did not become gods, swallowing the dragon yuan turned into a monster, the internal breath collapsed in vain, before the body died, the external things are vain after all, only their own penance is the right way.

The dragon vein is just to protect its own bones, the world is the world of the people of the world, and the people of the world must work together to make Shenzhou stable.

My backbone has the aura of the dragon clan, although it can suppress the demon of vain, but I hope that the person who sees this message will treat my skeleton well and not damage it. ”

The meaning of the translation is probably like this, Yu Nan suddenly laughed, this Yellow Emperor is also interesting, it doesn't matter if someone forcibly uses his spine as a dragon vein, and he deliberately set up a message to let people who don't want his backbone not to damage his bones.

Yu Nan didn't think about what the dragon vein had for him, but he just thought that it was good not to take the idea of a stupid fork, he put away the leather and went to the Yellow Emperor's skeleton and said with a smile:

"If I didn't see this thing, I was going to tear down your bones, and I was too greedy to take it when I saw it, but it's not safe for you to stay here, I'll find you a place to bury it, and no one will be able to find your bones in the future."

Taking out a jar from the belt space, Yu Nan began to pack the bones of the Yellow Emperor into it piece by piece, and when he turned around to find a safe place to bury the bones, the golden light in the hall shook and he quickly squinted.

When the golden light converged, a golden figure fluctuating in front of him opened his mouth and said:

"There are still people in the world who are not greedy like you, and my grandson Xuanyuan is worth waiting for."

Yu Nan saw the golden figure looking around, confirming that there was no projection equipment around, and couldn't help but ask:

"Uh, you...... What's going on? ”

The golden figure laughed:

"I am Gongsun Xuanyuan, this is a little Yuan Shen condensed by my whole body cultivation before I die, don't ask anymore, I should disappear after speaking."

Yu Nan blinked his eyes, he thought that this world was not an ordinary martial arts world, and there were many fantasy things in it, and it was normal for the Yellow Emperor to be able to condense the Yuan Shen and stay here, so he didn't continue to speak, and the Yellow Emperor Yuan Shen continued:

"Everything in heaven and earth has a cycle of life and death, and cultivators exist in order to transcend life and death and jump out of reincarnation.

Later, I found a secret after thinking about it, that is, the four elephants in this world are misplaced, the Dragon Island should be in the eastern sea, the phoenix should also be in the southern volcano, the turtle should go to the land of the North Sea, and the unicorn should also guard the western mountains;

But as a result, the turtle was deep in the mountains to the west, the phoenix went to the deserted place in the east, the dragon island was in the South China Sea, and the unicorn went to this middle earth cave.

If you want to break through, you have to absorb the power of the four spirits to cultivate the four spirit tricks, so that the four elephants in the body are balanced.

I will pass on the Four Spiritual Techniques to you now, and cultivating the Four Spiritual Techniques will not make you transcendent and holy, but it will allow you to obtain the Four Spiritual Qi without any mutation.

The head of the four spirits, the dragon raises its head, the end of the four spirits, the foot of the turtle, the body of the four spirits, the unicorn body, the qi of the four spirits, the blood of the phoenix, condenses the essence of the four spirits, and refines the balance of its own four elephants, if you get the five elements Shuntai, you can achieve transcendence......"

The Yellow Emperor kept saying, Yu Nan was not just silently memorizing and recording it, these four spirit tricks were not miraculous skills, but just let the four spirit qi balance their own effects, and when the Yellow Emperor finished narrating, Yu Nan looked up at him.

The Yellow Emperor's condensed spirit has become weaker and weaker, Yu Nan hugged the Yellow Emperor's skeleton jar and said:

"Senior Yellow Emperor, I will bury your bones well, and never let others disturb you again."

The Yellow Emperor smiled, and said in a smaller and smaller voice:

"Dragon's vein...... Only the earth can contain it, and I am only ...... alone."

In the final inaudible sound, the figure of the Yellow Emperor gradually dissipated, Yu Nan rushed out of the cave with the jar, in front of a cave that was only two feet in size swept by the scanner, he put the jar into it and completely sealed the hole with his palm, unless someone in this world scans the cave on a large scale like him in the future, almost no one can find the skeleton of the Yellow Emperor.

Over the next few days, the scanner had found seven or eight exits in the dense cavern, but each of them was in danger, either under a waterfall, on a cliff, or inside a crater.

On this day, Yu Nangang fused the essence of the Wuji Sword Method and the essence of the Six Techniques of Aohan, but an image fed back from the scanner made him happy and surprised.

In the picture, a dark red unicorn lies in a dry cave and squints and rests.

This was the first time he had seen a spirit beast like a qilin, and this was also the easiest target he planned to kill, the rare Yu Nan's heartbeat accelerated a little, and he clenched his fists and said to himself:

"Fire Qilin, today you are mine."

With the Five Elements Lost Trace Step combined with the strong legs to rush away, Yu Nan, who had already broken through the innate speed, was no less fast than the legendary wind god Nie Feng in the future, constantly flickering in the pitch-black channel, and even the sound of breaking the air that should have been there completely disappeared.

For most of the day, Yu Nan bypassed countless forks and reached the entrance of the Qilin Cave, and there was only one hole here on the scanner, which gave Yu Nan a huge opportunity.

The electromagnetic orbital gun was erected, and when Yu Nan slowly aimed the muzzle of the gun at the center of the fire unicorn's eyebrows, the fire unicorn seemed to open its eyes suddenly, and a fierce fire erupted from the cracks in the scale armor to surround it.

"Useless ......"

Just like hunting, even if the prey senses the crisis and is killed like an old hunter, Yu Nan has already locked the center of the fire unicorn's eyebrows, and he pulled the trigger before the fire unicorn stood up.

The blue light on the barrel of the electromagnetic railgun flashed, and a bullet the size of a finger left the barrel at an initial velocity of more than seven times the speed of sound, and the fire unicorn could not dodge at all, only to hear a pop of bullets that had pierced its head.
